| What are the differences between the Legacy 600 and the ERJ-145? Obviously besides that one is an executive jet, but I'm saying in the flight deck, size, systems, and other things. Isn't it the same flight deck at the 145? |

Brandon,
Just a few;
-IRS
-HUD
-Ventral tank system
-Different FADEC logic
It's based on the same airplane but it's more advanced. It can cross the Atlantic for example to the navigation (and of course the fuel) system needs to support this.
Thank you
Vic

Nice to see another feelThere bird on the market... Again an Embraer, again a Primus 1000 bird.
Regarding the Primus 1000 simulation you did extraordinarily well in the ERJ-145, I do have one or two minor remarks...
* For those who want to go 'right off the ramp' with the Legacy, the magic CTRL+E would be a good helper. The Legacy already has an engine autostart sequence so that wouldn't be a problem... same with the aural warning system. For people just wanting to fly this one "hands on" like a big Lear on steroids it may be possible to shut the aural warnings off and just take a VFR cruise at low altitude between two small fields.
* System simulation in the ERJ was great, but quite limited to the "APU is running, bleed air is available, so we can start the engines" kind of overhead logic. (Just a quick try: Disconnecting every hydraulic system on the plane *SHOULD* freeze the flight controls and even cause them to droop after a long time. You could still fly the PIC145 with all the hydraulics off.)... did you posess the original ERJ-145 manuals for this? I'd also really like to see some system-related things like engine fire and flameout simulation. Same with gustlock, it freezes the thrust levers but on the real bird it also blocks the control surfaces mechanically.
* Navigation and cockpit displays on the ERJ were spot-on. If you put a picture of a real ERJ next to your simulation, the result would be near identical, the only difference being the screen font on some occasions (since the ERJ uses the "old style" Primus 1000 vector based CRT's and stroked font text, for a Primus 2000 the Arial Narrow font is dead accurate)
* Get the ground power and bleed air connections right. The electricity connection is OK but I'm missing ground bleed air (as do many payware plane manufacturers miss out on that one)
* Will the Legacy feature the ERJ style CDU 810 or a "new" version of the CDU820 currently in use in the Legacy series? The 820 has loads of new features compared to the 810 courtesy of the FMZ2000 flight management computer that is running the whole thing.
* Can we finally get a few answers on how the "advisory VNAV" thing actually works? A real VNAV button would be cheating on a Legacy but I do get the magenta marker (like a glide slope marker) on the PFD with my ERJ. The only thing is, it's only being displayed and if I want to follow the FMC's descent path, I actually have to disengage the vertical mode on the A/P altogether.
* The Legacy is a bit smaller and thus also has different engines. Does that also mean a different sound set? IMO the APU was way too noisy on the ERJ.
* Do we finally get to touch the "reversionnary controls" on the Leg and the fire handles? Pieces of eye candy and great stuff to play with when you finally want something other than an uneventful flight.
* Does the navigation database finally get a tune-up? Every single procedure in the Netherlands published in AIP isn't in my ERJ database, not even the latest update. I know there are lots of versions of the AIRAC on the net via www.navdata.at, wouldn't it be possible to make a format converter? Most of the formats are just a plain text list of waypoints, airways, and terminal procedures. Just translating them into a different "language" would be completely harmless, unless other payware manufacturers happen to have patented their navdatabase format. Which I personally consider pretty silly because if you print it out and hang it on the wall it's a normal list.
One of my favorite things on a really good payware panel would be:
Double panel in Captain's and First Officer's configuration for
dual monitor users.
Or a great VC with really, really smooth displays is also good, not the thing you stuck in the old ERJ or even the 737 Classic.
Same bit, but a little more ambitious and one of my really great wishes for a payware manufacturer to do:
Undockable PFD/ND/EICAS displays and actually publishing the keyboard shortcuts or offsets to control those things! Interfacing with 'proprietary' aircraft is a huge issue in the flight deck building world and this would give you an enormous edge to people like Enrico Schiratti who don't take the regional jet market that seriously.
Being able to link two feelThere Legacies over a network or to an instructor station would be a definite dream come true. Other huge manufacturers wouldn't even ponder about those things. And they actually dare to call themselves "Precision Man..." when the only thing they do is blink a light and display an EICAS warning every time you flick the wrong switch on the overhead. Hell, I can even reconnect the GEN DRIVE's on that bird!
I'm also wondering a bit...
Since Embraer continues the Legacy line and decides to stop production on the ERJ-145 range, does that also mean new Legacies rolling of the line will have the Primus Epic system on board as opposed to the 1000 they used in the 145 (which is, honestly said, pretty obsolete for a newly produced 2006 bizjet)? I've yet to see the first Epic-driven plane for FS2004 to hit the market and I'm a huge fan of the Honeywell displays. I'm developing my own version of the Primus 1000 for use outside of Flight Simulator, and your ERJ-145 is the only payware aircraft I found worth buying since it has a Primus on board! |

Well I'm confused  . You demand realism and CTRL+E at the same time? Just like to said the Legacy has an autostart (simulated on the ERJ too). CTRL+E is not easier to push than turning a knob to a START position

The database remains the same as non of the current ddatabases are complex enough to drive our FMS. However just like in the case of the ERJ you can create and save your own procedure and recall it later from the FMS.

hydraulic controls have mechanical backup
Elevator even do not have hydraulics at all |

That's right, they are smaller on smaller jets (obviously), but they spin much faster. We've got a Legacy that comes into my FBO nearly everyday, and when I walk by it to get to my dinky 182T (did I mention G1000, baby  ), I feel like putting on my headset to block out the noise from the APU. It's rediculous. |

You're right, the FADEC/DEEC on the ERJ already does that job, but it can be a possibility to use the "classic" FS2004 engine model as an option (like changeable in the INI file or via the Configuration Panel). Not my kind of soup too, I want as much buttons as I can play with.

Does the 145 have mechanical backups for the F/C's then? Would make sense, but that would probably need some kind of changeover switch somewhere in the flight deck and a *lot* bigger control inputs for the same effect. Same with the gustlock lever, that's actually meant to lock the flight controls so they don't "blow away". And the fire handles would be a definite plus :)
quote:

I know I can follow the VNAV descent path with the TCS and the autopilot in Pitch Hold mode, but I often get warning messages from the FMC like "CHECK ALT CONSTRAINT" which were never mentioned in any manual. Most of the time I just cruise until TOD and then hit FLC until I'm at the bottom ;)

Same sounds then? The ERJ sounds great and I know it's pretty silent on the inside. But maybe it's a possibility to change the volumes of different systems (Aural Warning, avionics, APU if neccessary) via a little control panel? The avionics are usually controlled via the ACP which is next to the PFD.

The feelThere database format is pretty straightforward, it's an Access database with all waypoints/airways/procedures/whatnot in them. Other manufacturers use spare files for the same result, maybe I'll spend some time here and make a format converter from other payware manufacturers to the feelThere format. Biggest issue is that DAFIF only maintains the Atlantic and Pacific regions and (almost) totally skips Europe.

That wasn't my point. Read what follows it, I was talking about controlling the various Primus-specific functions on your bird via FSUIPC offsets or keystrokes. Or publish a documented API to control all feelThere-specific functions. Would be a real plus for us home cockpit builders ;)
That said, things like flight dynamics and exterior model were bang-on for the ERJ and I reckon they will be just as marvellous for the Leg. Most of the things I'm putting up here are pretty much "feature requests" for the panel. The regional / bizjet market for FS2004 is very small and things like this would give you a definite edge! |
